doi: 10.1038/s42003-023-05757-3
Figure Lengend Snippet: a LINC00689 , and ( b ) p-YAP1 (S127), YAP1, β-catenin, slug, vimentin, CTGF, CYR61, and HIF1α protein expression in CRC cells co-transfected with OE- LINC00689 and sh-LATS2 were examined by RT-qPCR and western blotting, respectively. β-tubulin was used as loading control for CTGF, and GAPDH was used as loading control for other proteins in western blotting. Red, blue, or purple outlines denote bands that were derived from the same blot. c CRC cell proliferative, ( d ) migratory, and ( e ) invasive abilities were evaluated after overexpressing LINC00689 and silencing LATS2 via CCK-8, wound healing, and transwell assays, respectively. Scale bar: 200 μm in d and 100 μm in e. f Immunofluorescence detection of N-cadherin expression after simultaneous overexpression of LINC00689 and knockdown of LATS2. Green, N-cadherin; Blue, DAPI. Scale bar: 50 μm. n = 3 biologically independent experiments in in vitro results. Data were presented as mean ± SD, * P < 0.05, ** P < 0.01, and *** P < 0.001. LATS2 large tumor suppressor kinase 2, OE overexpression, NC negative control, YAP1 yes-associated protein 1, CTGF connective tissue growth factor, CYR61 cysteine-rich angiogenic inducer 61, HIF1α hypoxia inducible factor 1α.
Article Snippet: RT-qPCR detection of KLF15 , LINC00689 , and LATS2 mRNA expression levels was performed with SYBR Green Master Mix (Applied Biosystems, Carlsbad, CA, USA) according to the manufacturer’s instruction on ABI7900HT (Thermo Fisher Scientific).
